DEVELOPMENT OF HARDWARE-SOFTWARE COMPLEX FOR THE DYNAMIC CHARACTERISTICS OF ENGINEERING STRUCTURES CONTROL
(pp. 57-61)

Abstract. A block diagram of hardware-software complex designed for the dynamic characteristics of engineering structures control is considered. Practical application of the developed complex under the dynamic characteristics obtained from monitoring the 9-storey block section before and after vibration testing with the load of 7 points is showed. Microdynamic informative method for field testing of 9-storey block sections of 1.120s series in Irkutsk has been studied. A significant (up to 16–26 %) reduction in the frequency of modal forms of block section after the dynamic load intensity up to 7 points on MSK-64 scale is showed. We found that control of the wave field increases the reliability of flaw detection and extends the possibilities of the method under the monitoring of the buildings condition.

Keywords: hardware-software complex, seismological monitoring, dynamic characteristics, microdynamic method, defect detection, the velocity of shear waves propagation in buildings.
